Application led April 2, 1906. Serial No. 309,556.

This invention relates to a signal apparatus designed more particularlyto provide hotels with means for ascertaining the room in which achambermaid is temporarily engaged. These means consist of anelectriclight bulb which is carried about by the maid and is inserted byber into a socket as soon as she enters a room. Sockets of this kind areprovided along the corridor, one being near the door of every apartment.The insertion of the bulb into the socket lights the former and at thesame time actuates an annunciator, so that the location of themaid isnot only indicated at the ofice, but also along the hall. Thus the maidalways remains in touch with the hotel management, the hallboys, and theguests, and need not be hunted up as heretofore.

In the accompanying drawings, Figure 1 is airont view of a row of roomsalong one side of a hall and provided with my improved signal apparatus;Fig. 2, a horizontal section through a hall; Fig. 3,'a front view of theannunciator, showing the Wiring; Fig. 4,'a detail of the socket andelectric-light bulb, and Fig. 5 a section through part of theannunciator.

Along one or both sides of the hall 9 are arranged the rooms or suites10 11 12, separated from the hall by the Walls or partitions 13. To theouter side of Wall '13 is secured near the. door 14 of each room asocket 15, having a iiaring mouth 16. Into this socket may be slippedthe end of an electric-light bulb 17, intended to be carried about bythe maid. In the hotel oiice is mounted an annunciator, composed of aboard 18, rovided with a number of Windows 19, Whic are numbered tocorrespond to the numbers 10 11 12, Sac., oitl the rooms. Back of eachWindow is an electric iight 20 in circuit With the socket 15 of thecorresponding room.

. The Wiring is suchthat When a bulb 17 is t the bulb and also toilluminate the cci);-

c l u u responding window of the annuncrator.

. shown, the feed-wire 2l connects by branch 22 with one Contact ofsocket 15. v The other contact of the latter communicates b a Wire 23With the corresponding lamp 20 o the annunciator, and thence by wire 24with feed- Wire 25.

'When the maid is about to enter, say, room l 1, she pushes her lamp 17into the socket 15 oisueh room. This Wiil at once cause the light toshow in front of said room, which light is clearly visible all along thehall. At the same time the annunciator will indicate to the hotelmanagement when and vWhere the maid is at Work. In this Way themovements oi' the maid are readily traced, and she rre-ay at all timesbe readily reached by the various occupants of the hotel.

What I claim is- `1. In a signaling system for hotels, a

'socket in. a hall on the exterior of a room, an

electric-light bulb adapted to removably engage the same, and anannunciator in circuit With the socket, substantially as specified.

2. In a signaling system for hotels, a series of rooms ranged along ahall, a series of sockets having flaring mouths and iitted along thehall, one near thedoor of each of the rooms, an electric-light bulbadapted to engage said, sockets, and an annunciator in circuit with thesockets, substantially as speciiied. l

3. In a signaling system for hotels, a socket in a hall on the exteriorof a room, a first electric-light bulb adapted to removably engage `thesame, an annunciator having a second electric-light bulb in circuit withthe socket, and means for lighting the second bulb by, the introductionof the first ub into the. socket, substantially as speci- Signed by Ineat New York city, (Manhattan,) New York, this 23d day ot' March, 1906.
